ABSTRACT:Setting up a model for the structural finite element, there are inevitably differences between the model and the real bridge .To make the model accurate it is necessary to update the model by using static performance results. In this paper, the optimization function of ANSYS is used to update the real bridge’s model. The final updated finite element model for the real beam is able to produce natural frequencies closer to the real ones .The updated is useful for the reference model to structure d... 更多
